Try resetting the alarm, using the instructions given at the link below. I'll also copy the text here.

Insert the ignition/door key in the door lock on the driver's- side door of your Mountaineer.

Turn the key to the lock position.

Turn your key to the unlock position.

Turn your key to the lock position.

Turn your key to the unlock position. Your alarm is now disabled. If your key fob works, you can also press the unlock or alarm-disable button on the fob.

Start the Mountaineer's engine and allow the vehicle to run for at least 10 minutes. This will allow the alarm to relearn the default settings. You must make sure that you have disabled the alarm first, however, before you attempt to start the vehicle, so that the alarm will reset itself.

If these instructions don't work, you can try resetting the car's computer by unplugging the battery for half an hour. However, that will reset the keyless entry code, as you can see in the fixya article I link to at the bottom

this alarm , if you forget any light on ( head light / parking light / fog /internal light ) it will contenuos . some time the glow box light or rear trunk light . it will alarm , check all light before you lock . maby you have one S.W have problem .

You need to find the black push button called the valet button. That is the overide. Get in the car turn the key to IGN as the alarm is going off and then you have either 5 or 10 seconds to push that button once and then 2-5 seconds later the alarm is shut off. To put the car into valet mode which means no alarm at all you put the key to IGN push that button once then pull key out at which point the blue light should turn solid blue.

Or option two is you open a door and hit the lock, then unlock, then lock button again on the remote and the blue led will be solid which means no crazy alarm.
